DIGITAL TACHOGRAPH DATA TRANSFER METHOD FOR VEHICLE TRACKING SYSTEMS

摘要

The invention relates to a digital tachograph apparatus (40) attached to digital tachographs (60) and enabling retrieval of data from digital tachographs (60), a VTS modem apparatus (30) attached to VTS modems (20), which are GSM/GPS modems used in the already available (prior art) vehicle tracking systems of relevant vehicle owner organizations, and a data management system (100) enabling wireless data transfer (via Bluetooth) through servers between digital tachographs (60) and VTS modems (20) by means of these apparatus.
